I've name changed just in case 😅
I lived in Richmond for about six years in my mid to late thirties while I was working Durham. I'm child-free. Before moving to Richmond I'd lived in London, then in Coventry, then in York, then in Harrogate. So, my response here is impacted by this wider context.
It's an absolutely beautifully stunning and peaceful place to live. There are some incredibly characterful properties in the town centre, and some lovely houses as you head out of town too. Compared to comparably lovely places in the south, properties are very cheap. But compared to other places around Darlington and County Durham, properties are expensive. I guess it depends on your budget and expectations.
I found there wasn't much going on in Richmond. While there was enough to do - a few community groups, some events in pubs, the leisure centre - it all felt a bit same-y. There wasn't anything fresh or new happening and I didn't feel particularly challenged or invigorated by the place. After three years I felt I was done with Richmond and, to be honest, quite eager to leave.
I met a lot of lovely people but there was a bit of a clique-y vibe to the place too and I never quite felt at home there. My DP used to say it was like Royston Vesey but I wouldn't go that far, it just didn't feel as friendly and welcoming as other place I've lived.
But I think a lot of that was impacted by me being in my 30s and child-free. I'd say Richmond was populated by a lot of retirees who'd lived there forever and young families who'd moved for a better life for their children. We didn't fit into either of these groups and, as I said, just didn't quite fit.
Edited to add (and prompted by another poster): Yes, it feels really incredibly remote which I think was compounded by the feeling I didn't quite fit in. Darlington is the nearest big-ish place and that's as grim as fuck.
